I mean, you can technically remove the default launcher entirely via ADB if you want to.
if you run windows, you can use Android TV Tools to run the ADB commands for debloat and launcher control without having to type them out, but there are plenty of guides to do it via ADB manually.
on Shield TV I was able to just install projectivy and set it as the default launcher, never had an issue after that, but i still do some debloat to remove extra google and nvidia background tasks and trackers.
